[PARISC] fix PA1.1 oops on boot

All PA1.1 systems have been oopsing on boot since

commit f311847c2fcebd81912e2f0caf8a461dec28db41

    parisc: flush pages through tmpalias space

because a PA2.0 instruction was accidentally introduced into the PA1.1 TLB
insertion interruption path when it was consolidated with the do_alias macro.
Fix the do_alias macro only to use PA2.0 instructions if compiled for 64 bit.
